  Carbon-roasted Tieguanyin tea is made by subjecting traditionally semi-fermented Tieguanyin tea to about 5-10 hours of charcoal roasting (hence its name). The fire must be carefully controlled, not too hot, with 50-60 degrees Celsius being optimal. Traditional charcoal-roasted Tieguanyin tea requires someone to tend the stove to ensure that the quality of the tea leaves themselves is not overly impacted. The carbon-roasted Tieguanyin has a unique aftertaste and flavor profile. After tasting it, one's throat feels particularly refreshed, carrying a subtle and refined charcoal aroma. Notably, the tea liquor turns a deep yellow after brewing, leaving a distinctive glutinous rice fragrance in the mouth.

Every type of tea has different benefits. When drinking tea, one must understand its properties and choose according to their own condition, which will promote health. At the same time, some teas should not be consumed together, which requires special attention from consumers. Green tea and wolfberry can both be brewed with boiling water for a healthy drink. Many people, for convenience, like to brew green tea and wolfberry together in the same teaware, but wolfberry and green tea should not be brewed together. Because they can absorb each other’s properties, when combined, they lose their medicinal efficacy and have little benefit to the body when consumed. The large amount of tannic acid in green tea has astringent and adsorptive properties, which can adsorb trace elements in wolfberry, forming substances that are difficult for the human body to absorb. In popular restaurant blends of eight-treasure tea, there is both green tea and wolfberry, although the amount of green tea is relatively small, it still should not be consumed excessively. Wolfberry is sweet in taste and neutral in nature. In Traditional Chinese Medicine, it is used to treat yin deficiency of the liver and kidneys, weakness in the lower back and…

Tea leaves will undergo changes over time, regardless of whether they are vacuum-packed. The chlorophyll and polyphenol compounds in the tea can cause the leaves to age and turn yellow or red. If the tea was not sufficiently dehydrated or dried improperly, the infusion may become bitter and astringent. If stored improperly, it may even develop mold. Therefore, when you return to drinking tea that has been opened for some time, there are certain issues to be mindful of. First, check if the tea has developed mold. Place the tea leaves in your hand and examine them under bright light or give them a light sniff. If there is a musty smell, the tea should not be consumed and can instead be used as plant fertilizer. Brewing Method to Address the Issue If the dry tea leaves have a grassy scent or other off-flavors, you can seek the assistance of a professional tea roaster or a tea shop to process them. If there is only a slight aged or stale flavor, you can use a brewing method to address this. Method One The water temperature should be high, ideally boiling.
